Achieving accurate measurement of extra low flow rates has been a known challenge for many metering technologies across several industries. Even though traditional metering options are commercially available these come with some undesired effects such as pressure drop and are prone to wear and tear and drifting over time. These ultimately impact measurement accuracy and repeatability, not to mention being costly to install in retrofitted applications and requiring constant maintenance and calibration.

Understanding that flow rate measurement provides one of the most im-portant process parameters in the chemical, pharmaceutical, petroleum, energy, and power engineering industries, FLEXIM continues to develop and improve our extra low flow capabilities and signal processing techniques and introduces the FLUXUS® F721XLF ultrasonic clamp-on meter.

The new FLUXUS® F721XLF can achieve accurate and reliable measurement of flows as low as 1 gph or 0.01 gpm and below in small pipes and tubes 3/8 to 2 inches, provides bidirectional communications protocols, matched transmitter and transducer calibration as well as aluminum and stainless-steel housing options.

Flow

Chemical Injection for Oil & Gas______

Scale and corrosion inhibitors are used in the Oil & Gas industry to prevent scale build-up on pipes and to maintain well integrity. Accurate measurement of these costly chemicals means that oil companies can keep costs down while ensuring optimum flow is maintained.

Upstream: Exploration and Production Sea Water Treatment pre water injectionInjection of organic biocides as corrosion inhibitors is commonly used in offshore environments to reduce the abrasiveness and solid particles of sea water prior to injection. Due the high cost and quantities needed, these are dosed weekly for a period of 1 to 2 hrs at concentrations up to 1000 mg/l and require reliable and accurate flow measurement.Removal of Salt on Gas producing wellsPrecipitation of salt from reservoir water in gas reservoirs can cause significant decrease in production rates and pipeline blockages. In order to remove salt deposits freshwater treatments are performed at regular intervals to wash out the salt safely. In these applications small amounts of pure water are injected a high pressure and low flow rates to wash out the salt. Due to abrasive nature of the salt particles inline metering is often not suitable.

Midstream: Underground Gas StorageHydrate Inhibitor Injection Methanol Injection is routine in Underground Storage operations to mitigate hydrate formation and minimize blockages of valves and pipelines during withdrawal stages. Injecting substances to lower freezing points thus limiting hydrate formation needs to be carefully dosed, monitored and controlled. Typical application will employ a combination of high pressure and low flow injection to ensure proper mixing with the gas medium.

Chemical dosing in Water and Wastewater treatment______

Specialized chemicals such as chlorine, hydrogen peroxide, sodium chlorite, and sodium hypochlorite (bleach) act as agents to disinfect, sanitize, and assist in the purification of wastewater at treatment facilities. These need to be handled and measured carefully and meticulously to comply with safety regulations.
